Advancing Inverse Sensitivity/Uncertainty Methods for Nuclear Fuel Cycle Applications
Arbanas, G., Williams, M. L., Leal, L. C., Dunn, M. E., Khuwaileh, B. A., Wang, C., & Abdel-Khalik, H. (2015, January). NUCLEAR DATA SHEETS, Vol. 123, pp. 51–56.
TL;DR:
It is shown how the IS/UQ method could be applied to systematic and statistical uncertainties in a self-consistent way and how it could be used to optimize uncertainties of IBEs and differential cross section data simultaneously.

GENERALIZED PERTURBATION THEORY-FREE SENSITIVITY ANALYSIS FOR EIGENVALUE PROBLEMS
NUCLEAR TECHNOLOGY, 179(2), 169–179.
author keywords: generalized perturbation theory; reduced order modeling; sensitivity analysis
TL;DR:
This paper introduces a reduced-order modeling approach based on subspace methods that requires the solution of the fundamental adjoint equations but allows the generation of response sensitivities without the need to set up GPT equations, and that provides an estimate of the error resulting from the reduction.
